Precautions
!
Do not use Electro-Voice loudspeakers in an environment where temperatures
are below 0°C (32°F) or exceed +40°C (104°F).
!
Never expose an Electro-Voice loudspeaker to rain, water, or high moisture.

levels sufficient to cause permanent hearing damage to anyone within normal
coverage distance. Caution should be taken to avoid prolonged exposure to
sound pressure levels exceeding 90 dB.

Suspension
!
Warning!
Suspending any object is potentially dangerous and should only be attempted by individuals
who have a thorough knowledge of the techniques and regulations of suspending objects
overhead. Electro-Voice strongly recommends all loudspeakers be suspended taking into
account all current national, federal, state, and local laws and regulations. It is the
responsibility of the installer to ensure all loudspeakers are safely installed in accordance
with all such requirements. When loudspeakers are suspended, Electro-Voice strongly
recommends the system be inspected at least once per year or as laws and regulations
require. If any sign of weakness or damage is detected, remedial action should be taken
immediately. The user is responsible for making sure the wall, ceiling, or structure is capable
of supporting all objects suspended overhead. Any hardware used to suspend a loudspeaker
not associated with Electro-Voice is the responsibility of others.

industrial design — with robust wood enclosures and durable EVCoat finish — ensures that EKX
speakers look as great as they sound.
Passive EKX models deliver up to 134 dB SPL utilizing high-sensitivity transducers designed
and engineered by EV (12-inch EVS-12M woofer / 15-inch EVS-15M woofer, each coupled with
a DH-1M 1-inch titanium compression driver; 15-inch EVS-15C subwoofer / 18-inch EVS-18C
